Description

Technical Field

[0001] The utility model belongs to the technical field of water purifiers, and more specifically relates to a sterilizing water outlet nozzle. Background Art

[0002] In daily life, people need to obtain drinking water through pipes, water storage devices, etc. However, during the transportation process, drinking water itself carries various pathogens and is prone to breed bacteria. If it is drunk directly, it will have an impact on the human body. It usually needs to be sterilized before it can be drunk.

[0003] The traditional practice is to add chlorine, hydrogen peroxide and other disinfectants to the water. However, with the rise of ultraviolet sterilization, the current common disinfection method in the market is to use ultraviolet light to directly irradiate the drinking water pipeline to sterilize it, or to install a sterilization device at the faucet for sterilization. Although ultraviolet sterilization wins by virtue of its non-toxic, harmless and residue-free physical properties, it also cannot directly reflect its sterilization efficiency, and the user experience is poor; on the other hand, in general, the electrical power can be calculated by monitoring the voltage and current, and then the optical power of the ultraviolet LED chip can be calculated based on the electrical power and the electro-optical conversion rate. However, when the ultraviolet LED chip loses its life due to long-term use, its electro-optical conversion rate also decreases, and it is even more impossible to determine whether the sterilization rate meets the requirements.
